ELECTRIC-LIGHT-BULB SHIELD.

Specification of Letters Patent.

'Patented Dec. 1, 1908.

Application filed. March 18, 1908. Serial No. 421,843.

.To all whom it may concern:

Be it known that I, BENJAMIN R. WIL- LIAMS, a citizen of the United States, residing at English, in the county of J eferson and State of Arkansas, have invented certain new and useful Improvements in Electric-Light-Bulb Shields, of which the following is a specification.

My invention has relation to electric light bulb shields, and consists in a shield of two or more parts, adapted to be removably secured to the electric light bulb socket, and to be shifted from side to side on the same.

The bulb may be round, oval, sphereshaped, or of any other appropriate shape, in which case the shields will conform to the shape of the bulb.

'lhe shields are intended to shade the light, and they may be of any color, and in use, both shields may be of the same color, or may be-eilmdiiqlenmcolors. m

The invention is so constructed that only one shield may be used at a time, or both may be used at the same time, and the invention is so constructed that one or both of the shields may be removed, or one may be slipped around so as to cover the other one, and thus have a double shade on one side of the bulb, leaving the other side of the bulb open to throw its full light; thus any part of the room may be partly darkened, while the other part may be brilliantly lighted up.

In the accompanying drawings, Figure l, is an elevation, partly in perspective, partly in section and partly represented by dotted lines, of a socket and an electric light bulb, with my shields attached thereto. Fig. 2, is an elevation of the socket in perspective, and the other parts of my invention in section. F ig. 3, is a cross-sectional view of Fig. l, on the line a' m, showing an additional half band 9. Fig. 4, shows a crosssectional view, in modified form, of Fig. 2, on the line a e, showing the necks of the shields in cross-section, but the neck of the socket and lining thereof are not in crosssection, and the half band 9, is not shown in this view. Fig. 5, is a cross-sectional view of Fig. l, on the same line m oo, showing the neck of the socket and the shields, all in cipss-section, the binding-band being left o Referring more particularly to the drawings, the numeral l, represents the socket; 2, the key, through the medium of which the electric circuit is turned on or 0E 3, represents the neck of the socket; 4, the lining of the neck; 5, the bulb, which is screwed into the neck of the socket; 6 and 61, represent the shields; 62 63, the necks of the shields; 7, an annular ridge, surrounding the neck of the socket near its lower end; 8, represents annular grooves in the inner faces 0f the necks of said shields, which fit over said annular ridge; 9, represents a half band, which encircles the neck of the socket and extends half way around the same; 10, the binding-band; 11, the perforated ears and 12 a threaded binding screw, which passes through the perforations of said ears.

It will be observed that in Fig. 1, I represent the socket 1, key 2, neck to the socket 3, lining to the socket 4, bulb 5, shields 6 and 61, the binding-band 10, ears to binding-band, l1, and binding-screw 12, but in Fig. 3, I do not show the lining 4, to the neck, but I show an additional half band 9.

In Fig. 5, I show the neck 3, lining 4 and necks 62 and 63 of the shields 6 and 61.

In Fig. 4, the necks 62 and 63 of the shields are in section, but the neck of the socket and lining to the neck are not in section.

The operation of my invention is as follows The shields 6 and 61 are so formed at their edges that they slightly overlap each other, so that there may be no crack left between the edges of the same for the white light to pass through. lVhen I desire the whole room to be darkened, or the light to be modiiied, I put the shields 6 and 61 in their proper place, and hold them there by means of the binding-band 10 and screw l2. If I desire only part of the room darkened I slip the shield 6l around over the shield 6, and therefore have on that side of the bulb a double shield, while the other side is open. In this case the shield 61 is a little larger than the shield 6 and conforms to the curve of the half band 9,which holds the shield 61 out a little beyond the immediate track of the shield 6.

In my modified form I do notl use the eX- tra half band 9, and when I wish to darken only part of the room, I loosen the bindingband, and entirely remove one of the shields.

Although I have specifically described the combination, construction and arrangement of the several parts of my invention I do not confine myself particularly to such specific combination, construction and arrangement, as I may claim the right to make such modication and changes therein as may clearly fall within the scope of my invention, and which may be resorted to without departing from the spirit, or sacrificing any of my patentable rights therein.

Having described my invention, what I claim as new and desire to secure by Letters Patent, is

l. In combination with an electric bulb socket l, an annular ridge 7, around the neck 3, of said socket near its lower end; a pair of shields 6 and 61, adapted to sur- -round the bulb 5, said shields adapted to overlap each other at their edges, each being provided in their necks with internal annular grooves 8, adapted to fit over said ridge 7 a half band 9, fitting half way around said neck of said socket; a binding-band l0, provided with perforated ears 1l, fitting around the necks of said shields, and adapted to hold said shields in place, and a threadto fit the neck of said socket, one of said,

shields being slightly larger than the other and adapted to slip over the same, and a binding-band adapted to encircle the necks of said shields, and hold the same in place, substantially as shown and described and for the purposes set forth.

In testimony whereof I aiX my signature, in presence of two witnesses.
